Answer: 7/3
Step-by-step explanation:
To divide fractions, you can use the "keep, change, flip" method.
1. Keep the first fraction (7/9) as is.
2. Change the division sign to a multiplication sign.
3. Flip the second fraction (i.e. find the reciprocal). This means 1/3 changes to 3/1.
Rewrite the equation:
7/9 x 3/1
Multiply the numerators and the denominators together, respectively.
21/9
Simplify:
7/3

Answer:
Step-by-step explanation:
<u>Use the law of cosines:</u>
- cos C = (25² + 27² - 28²)/(2*25*27)
- cos C = 0.4222
- m∠C = arccos 0.4222
- m∠C = 65°
